Description

  The present invention relates to a multi-use charging system having a transmission function, in particular, charging a portable device, supplying power to a device connected to a USB port, and enabling data transmission to connect the portable device to an Ethernet. The present invention relates to a multi-use charging device and a multi-use charging system that can be performed.

  Currently, light and convenient portable devices such as mobile phones and personal digital assistants (PDAs) have already been deeply incorporated into people's daily life and work. These portable devices are not only convenient to carry because of their small size and light weight, but they can be provided with various functions as the technology advances recently. For example, it provides people with great convenience in all aspects such as wireless communication, rapid information retrieval, data input, and transmission function.

  Generally, the problem of power consumption in the above-described portable device has always been one of the very important technical issues in system design. For example, when directly transferring data between a peripheral device (for example, USB portable memory, memory stick adapter, etc.) having a USB (Universal Serial Bus) port interface and the portable device, a USB host chip is installed in the portable device. However, it is necessary to make a USB connection with the peripheral device. In that case, the portable device needs to supply power to the peripheral device, and must consume extra power. That is, when the portable device and the peripheral device perform data transmission with each other, a large amount of power is consumed in the portable device (the rechargeable battery), and in general, stable power supply can be performed. Data transmission and Ethernet online connection (from a portable device) were performed via a desktop PC or notebook PC.

  However, when it is desired to directly transmit data between the portable device and the peripheral device without using a desktop PC or notebook PC, it is possible to use a charger of the portable device. In that case, when the USB host chip to be mounted is connected to the peripheral device via the USB connector and data transmission is performed, the portable device uses the charger (power adapter) of this portable device and always uses the power for data transmission. Supply must be secured.

  For example, FIG. 1 is a diagram showing a conventional portable device system incorporating a USB host chip. As shown in FIG. 1, the portable device system includes a portable device 1, a peripheral device 4, a USB transmission line 3, and a power adapter 2. The portable device 1 includes a USB host chip 10, a USB connector 12, and a rechargeable battery 14, and the USB host chip 10 is coupled to the USB connector 12.

The peripheral device 4 has a USB port 40, and the USB port 40 is electrically connected to the USB connector 12 via the USB transmission line 3. In this state, power is supplied from the portable device 1 to the peripheral device 4, and data transmission is performed.
The power adapter 2 that is a charger has a voltage converter 20 and a charging plug 22, and the charging plug 22 is electrically connected to the voltage converter 20. The voltage converter 20 applies a necessary voltage to the portable device 1 to charge the rechargeable battery 14, so that the portable device 1 ensures a normal power supply during data transmission.

  However, in this conventional system, as described above, it is necessary to always supply power from the portable device 1 to the peripheral device 4 at the time of data transmission. There was a problem that the charging efficiency to 14 decreased.

Further, referring to the conventional “mobile phone transmission device” of Patent Document 1, the mobile phone has a problem that it can only perform data transmission and charging to a peripheral device via a notebook PC.
